// Package harness serves a fixture in a real Chromium: the browser rig
// behind `go test -tags browser ./...`.
//
// Every other file in this package is build-tagged `browser`. The root
// package promises that chromedp stays out of the ordinary build graph
// (`go list -deps .` pulls none of it), and an untagged package
// importing chromedp would make that sentence false the day it landed.
// This doc file is what keeps a plain `go build ./...` and
// `go vet ./...` seeing a valid package; the rig itself exists only
// under the tag.
//
// The shape is rastrillo's harness without the virtual authenticator
// (spec: rastrillo's docs/superpowers/specs/2026-08-23-harness-design.md):
// New binds a localhost listener first, hands the fixture its origin,
// then launches Chromium; watchers make every console error, failed
// request and 4xx/5xx a test failure; Screen gates each screen behind
// the junk scan, the bug class that renders perfectly and says nothing.
